+Subject: [PATCH 01/19] fix shutdown crash
+
+Backport of upstream fix from
+https://git.gnome.org/browse/gdm/commit/?id=e980b9101bfb1387df3cab4bf0c5ebdb4c6badbb
+
+local-display-factory: disconnect signal handlers when factory is disposed
+
+There's the potential for a crash in the shutdown path after the
+factory is disposed, since we fail to disconnect signal handlers to
+the displays / display store at factory dispose time.
+
+This commit changes the g_signal_connect to g_signal_connect_object, to
+avoid any potential for crash.
+
+(this is a fix noticed when reading through the source.  It's tangentially
+related to a discussion on irc for a different bug)
